Description

This configuration was tested on NetScaler 11.0 releases and is intended to configure NetScaler as a DHCP Relay Helper.  
The idea on this example is to create the relay helper, which is going to listen on a specified VLAN only.
 

Instructions

Create a service group and LB vserver:

add serviceGroup dhcp-service-group DHCPRA -maxClient 0 -maxReq 0 -cip DISABLED -usip NO -useproxyport NO -cltTimeout 120 -svrTimeout 120 -CKA NO -TCPB NO -CMP NO -appflowLog DISABLED
 
add lb vserver vip-dhcp-vlanfilter DHCPRA * 67 -persistenceType NONE -Listenpolicy "CLIENT.VLAN.ID.EQ(###)" -cltTimeout 120 -appflowLog DISABLED
 
Then proceed bindings services to the LB vServer.
  • bind lb vserver vip-dhcp-vlanfilter dhcp-service-group
 
  • bind serviceGroup dhcp-service-group serverA 67
 
  • bind serviceGroup dhcp-service-group serverB 67
 
  • bind serviceGroup dhcp-service-group -monitorName ping
 
After this, NetScaler will be able to forward DHCP information to the desired DHCP server.
